1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

introductionAlthough pilomatrixomas are frequently encountered by dermatologists and pathologists in the differential diagnosis of head and neck lesions, this is not usually the case among head and neck surgeons. A pilomatrixoma (calcifying epithelioma of Malherbe) is a benign tumour of the hair matrix cells. Histologically it is characterised by the presence of ghost cells, basophilic cells and foreign body cells. It may sometimes be difficult to histologically distinguish it from its malignant counterpart, the pilomatrix carcinoma. We report an interesting case of an ulcerated pilomatrixoma of the pinna in a middle-aged Caucasian female. CASE PRESENTATION: A 46-year-old Caucasian female presented with a one-month history of tender brownish lump on the pinna. Initially it was thought to represent a pyogenic granuloma. The lesion was treated by wide circular excision. Histopathological evaluation reported a benign calcifying epithelioma of Malherbe.

conclusionA search of the world's literature has led us to believe that this is a rare case of a calcifying epithelioma of Malherbe of the pinna. The rapid growth and ulcerative nature of this tumour makes this case even more unique.
